Answer:
21 miles per gallon
Step-by-step explanation:
The formula for slope is

Using the points (0, 0) and (1, 21), we have
m = (21-0)/(1-0) = 21/1 = 21
This means they get 21 miles per gallon of gas.
Both x and y intercept equal 2 ( to find x, make y = 0 and vise versa to find y)
x-int: 4(0)+y=0
0+y= 2
y=2
y -int: 4x +0=2
4x=2
x=2
